Preface
This document helps customers with data security concerns to sanitize or remove memory devices from the RSA5100B
Series Real-Time Signal Analyzers.
These products have data storage (memory) devices and data output devices (USB ports). These instructions tell how to
clear or sanitize the memory devices and disable the data output devices. The instructions also tell how to declassify an
instrument that is not functioning.
Reference
The procedures in this document are written to m eet the requirements specified in:
NISPOM, DoD 5220.22–M, Chapter 8
ISFO Process Manual for Certification & Accreditation of Classified Systems under NISPOM
Products
The following Tektronix products are covered by this document:
RSA5103B
RSA5106B
RSA5115B
RSA5126B
Terms
The following terms may be used in this document:
Clear.
This removes data on media/memory before reusing it in a secured area. All reusable memory is cleared to
deny access to previously stored information by standard means of access.
Erase.
This is equivalent to clear.
Instrument Declassification.
A term that refers to procedures that must be undertaken before an instrument is
removed from a secure environment. Declassification procedures include memory sanitization and memory removal,
and sometimes both.
RSA5100B Series Declassification and Security Instructions iii
Preface
Media storage/data export device.
Any of several devices that can be used to store or export d ata from the
instrument, such as a USB port.
Power off.
Some instruments have a “Standby” mode, in which power is still supplied to the instrument. For the
purpose of clearing data, putting the instrument in Standby mode does not qualify as powering off. For these products,
you will need to either press a rear-panel OFF switch or remove the power source from the instrument.
Remove.
This is a physical means to clear the data by removing the memory device from the instrument. Instructions
are available in the product Service Manual.
Sanitize.
This eradicates the data from media/memory so that the data cannot be recovered by other means or
technology. This is typically used when the device will be moved (temporarily or permanently) from a secured
area to a non-secured area.
Scrub.
This is equivalent to sanitize.
User Accessible.
User is able to directly retrieve the memory device contents.
User-modifiable.
The user can write to the memory device during normal instrument operation, using the instrument
interface or remote control.
Vo latile memory.
Data is lost when the instrument is powered off.
Nonvolatile memory.
Data is retained when the instrument is powered off.
iv RSA5100B Series Declassification and Security Instructions
Clear and Sanitize Procedures
Memory Devices
The following tables list the volatile and nonvolatile memory devices in the standard instrument and listed options.
Detailed procedures to clear or sanitize these de vices, if any, are shown following each table.
Terminology
The following terms are used in the tables in this section:
User data – Describes the type of information stored in the device. Refers to waveforms or other measurement data
representing signals connected to the instrument by users.
User settings – Describes the type of information stored in the device. Refers to instrument settings that can be
changed by the user.
Both – Describes the type of information stored in the device. It means that both user data and user settings are
stored in the device.
None – Describes the type of information stored in the device. It means that neither user data nor user settings
are stored in the device.
Directly – Describes how data is modified. It means that the user can modify the data.
Indirectly – Describes how data is modified. It means that the instrument system resources modify the data and that
the user cannot modify the data.

4 RSA5100B Series Declassification and Security Instructions
Clear and Sanitize Procedures
Clearing Hard Disk Drives
If your organization's security protocols allow the use of software to purge or sanitize hard drives, you can use commercial
software to erase free space on the hard drive before sending the instrument out for upgrades or repair. Follow the
instructions that come with the software to ensure that the erasure of sensitive data from the hard drive complies w ith your
organization's security protocols.
Sequence for clearing s ecure data from a hard drive:
1.
Delete all stored signals and instrument settings files (all files stored with a
tiq
,
csv
,or
Setup
extension).
2.
Acquire several full memory-length acquisitions of noise (no signal attached to the input).
Without Option 53, acquire a full-length acquisition 4 times.
With Option 53, acquire a full-length acquisition 16 times.
3.
Close the RSA5100B application and erase the free space on the hard disk using commercial software.
Fixed Hard Drive Removal
Procedure
The following procedure applies to instruments with Option 59 (Fixed Hard Disk Drive) installed. This procedure is a n
overview of the removal process. For detailed removal and replacement procedures, see the RSA5100B Series Real-Time
Signal Analyzers Service Manual, Tektronix part number 077-0903-XX.
WARNING.
Only qualified service personnel should perform this procedure. Read the Service Safety Summary and the
